I have two problems while using interclient 3.0 JDBC driver in JAVA :
* I loose any special characters stores in Interbase database field while reading in JAVA. I suppose, it comes from charset encoding. But what if i do not know what it the charset used by database ?
* Other problem is that interclient does not give error code after raising an SQL esception. It's always set to 0. Is there a way to get more than the error message ?

Thanks for answers.
